ABSTRACT

In one example, a charging filtering function may obtain a request for one or more rules that control whether or when one or more charging data records associated with a user equipment are to be provided to one or more billing systems. The request includes an identification of the user equipment. Based on the identification of the user equipment, the charging filtering function may identify the one or more rules. The charging filtering function may provide the one or more rules to control whether or when the one or more charging data records associated with the user equipment are to be provided to the one or more billing systems.

TECHNICAL FIELD

The present disclosure relates to telecommunications technology.

BACKGROUND

As fifth generation (5G) cellular networks are increasingly adopted and deployed, charging volumes/transactions are expected to grow and fluctuate dramatically. In 5G, network functions can be dynamically instantiated and scaled, and are expected to support tens of millions of devices. There will likely be millions of transactions per second, which may potentially grow to trillions of transactions per day in the near future.

DESCRIPTION OF EXAMPLE EMBODIMENTS

Overview

In one example embodiment, a charging filtering function may obtain a request for one or more rules that control whether or when one or more charging data records associated with a user equipment are to be provided to one or more billing systems. The request includes an identification of the user equipment. Based on the identification of the user equipment, the charging filtering function may identify the one or more rules. The charging filtering function may provide the one or more rules to control whether or when the one or more charging data records associated with the user equipment are to be provided to the one or more billing systems.

Example Embodiments

FIG. 1 illustrates a block diagram of an example system 100. System 100 includes network function 110, converged charging system 120, and billing system 130. Converged charging system 120 includes Charging Function (CHF) 140, Account Balance Management Function (ABMF) 150, Charging Gateway Function (CGF) 160, Rating Function (RF) 170, and Charging Filtering Function (CFF) 180.

Network function 110 may be a Session Management Function (SMF) configured to provide charging events (e.g., usage record generations) to converged charging system 120 (e.g., over the Nchf interface) on behalf of a User Equipment (UE). Converged charging system 120 may in turn generate Charging Data Records (CDRs) based on the charging events and provide the CDRs to billing system 130 (e.g., over the Bx interface). The charging events and CDRs may be associated with the UE. Billing system 130 may be a north-bound Operations System Support (OSS) end system configured to charge in online or offline billing mode. Billing system 130 may have any suitable entity associated therewith (e.g., enterprise, operator, Internet of Things (IoT) entity, etc.).

CHF 140 may be configured to obtain the charging events from network function 110, generate the CDRs, and provide the CDRs to CGF 160. ABMF 150 may be configured to provide, to CHF 140, information regarding one or more balances associated with an account of the UE. CGF 160 may be configured to obtain the CDRs from CHF 140 (e.g., obtain reports of creation and release of charging records such as CDR storage locations), process the CDRs, and provide the CDRs to billing system 130. RF 170 may be configured to provide, to CHF 140, information regarding a charging rate(s) corresponding to the charging events. CHF 140 may generate the CDRs based on the information obtained from ABMF 150 and RF 170.

Network traffic in cellular networks is growing rapidly, and a correspondingly large number of charging events is increasingly provided to converged charging systems. This will place an enormous load on existing north-bound charging systems (e.g., online/offline billing systems configured for billing and rating functions) hosted in the cloud to handle the increased traffic and variabilities. A conventional converged charging system would generate a multitude of CDRs, corresponding to the large number of charging events, and provide the CDRs to a billing system. The large volume of CDRs could require an inordinate amount of bandwidth, overwhelming the converged charging system, the Nchf and/or Bx interfaces, and/or the billing system.

Accordingly, CFF 180 is provided to manage rules that control whether or when one or more CDRs are to be provided to billing system 130. Briefly, CFF 180 may obtain a request for one or more rules that control whether or when one or more CDRs associated with a UE are to be provided to billing system 130. The request includes an identification of the UE. Based on the identification of the UE, CFF 180 may identify the one or more rules and provide the one or more rules to control whether or when the one or more CDRs associated with the UE are to be provided to billing system 130.

CFF 180 may thereby reduce the required load by filtering/avoiding/skipping unnecessary traffic (e.g., CDRs), instead of permitting every CDR to be sent to billing system 130. This may be useful/economical for both network operators and one or more entities associated with billing system 130. These techniques may provide efficient integration with 5G network providers while reducing the operational costs (and increase efficiency) by leveraging CFF 180 in the underlying architecture to filter out unnecessary traffic.

With continued reference to FIG. 1, FIG. 2 illustrates a block diagram of an example system 200. System 200 includes network function 110, converged charging system 120 (including CHF 140, CGF 160, and CFF 180), and billing system 130. System 200 also includes Control Center 210 and third-party services 200. Control Center 210 may be any suitable control center, such as an IoT Control Center, a Communication Service Management Function (CSMF), etc. Control Center 210 may include a provision for one or more entities to define one or more filtering rules/policies and push the rules to CFF 180. Third-party services 220 may be any suitable service, such as a location-based service that indicates a location of a UE (e.g., location-based services, location changes, etc.).

As further shown, CFF 180 includes various functional components to manage one or more rules that control whether or when one or more CDRs are to be provided to billing system 130. CFF 180 includes CHF interactor 230, rules engine 240, notification service 250, and rules repository 260. CHF interactor 230 may support different filtering behaviors for various event types by obtaining, from CHF 140, a charging filter request to filter one or more CDRs and providing an appropriate response to CHF 140. The filter request sent by CHF 140 may include a UE identifier (e.g., a Subscription Permanent Identifier (SUPI)), the units of usage for the session in which the UE is participating, and an operation type indicating whether the request is to create, update, or release a charging record. CHF 140 may use the response to provide a converged charging service.

Rules engine 240 may support operations to add/modify/delete rules. In particular, rules engine 240 may enable an entity associated with billing system 130 to define different types of rules to support filtering behavior. The rules obtained from billing system 130 may include the rule type, the range of SUPIs to which the rule(s) apply, and any trigger(s) that should be used for the set of devices. In the absence of SUPI values, the rule(s) may apply to all devices/triggers. Rules engine 240 may also determine the type of filtering rules matched against a generated charging volume and direct CHF interactor 230 to provide appropriate response triggers to CHF 140. Any suitable type of rule may be utilized, such as a usage type, a rate-limit type, or a custom type.

A usage type rule may control whether one or more CDRs associated with a UE are to be provided to one or more billing systems (e.g., billing system 130) based on an amount of information to be carried in the one or more CDRs. For instance, a usage type rule may be a rule that requires that reported charging data have a minimum volume (e.g., in bytes) to consider the reported charging data for CDR processing. This may prevent any CDRs below a given volume threshold from being sent to billing system 130. In one specific example, a usage type rule may cause CFF 180 to intelligently identify zero-byte CDRs, which are typically used as keep-alive messages even when the UE is not in use, as benign transactions that should be suppressed/dropped. This rule may permit non-zero-byte CDRs, which indicate transactions that require rating/balance updates for converged charging system 120, to be provided to billing system 130. Thus, a usage type rule may control whether or not CDRs are to be passed on to one or more billing systems.

A rate-limit type rule may control when one or more CDRs associated with a UE are to be provided to one or more billing systems (e.g., billing system 130) based on a frequency at which the one or more CDRs are to be provided to the one or more billing systems. For instance, such a rule may indicate that one or more CDRs are to be provided to billing system 130 once every given number of minutes (e.g., fifteen minutes, thirty minutes, etc.). Thus, in one example, CFF 180 may intelligently rate-limit (e.g., control the rate of) charging events triggered towards CHF 140 in order to limit the rate of volume traffic.

A custom type rule may include any suitable custom rule specified, for instance, by an entity associated with billing system 130. The entity may specify the custom rule through a policy management User Interface (UI). The custom rule may control whether or when one or more CDRs associated with a UE are to be provided to billing system 130 based on a location of the UE. Such a rule may indicate that a given usage threshold or rate limit is to apply when a UE is in a given location. For example, CDR generation may be rate-limited to once every thirty minutes when the UE is in a roaming location. Notification service 250 may obtain updates from third-party services 220 regarding certain events (e.g., UE location changes between a home location and a roaming location) in order to support CDR filtering behavior according to the custom rule(s).

Rules repository 260 may store/maintain a mapping defining various rules that control whether or when one or more CDRs associated with a UE are to be provided to billing system 130. Rules repository 260 may define different filtering behaviors for the UE (e.g., usage generation checks, rate-limit record generation, etc.) based on the different types of filtering policies/rules (e.g., usage, rate-limit, custom, etc.). The rules may be defined/established by the entity associated with billing system 130 to support various filtering behaviors. Rules repository 260, in conjunction with rules engine 240, may thus enable CFF 180 to enforce rules defined by the entity associated with billing system 130.

Table 1 below illustrates example rules that may be stored by rules repository 260. The numbers in the “Threshold” column may be measured in bytes, and the numbers in the “Rate Limit” column may be measured in seconds.

TABLE 1 Rule Rule Min Max Rate ID Type Description SUPI SUPI Threshold Limit Custom Trigger 1-1 Usage Suppress CDR 10001 10010 5 NA NA generation for usages <5 1-2 Usage Suppress CDR 10010 30000 15  NA NA generation for usages <15 2-1 Rate Limit generation 30001 30010 NA 1800  NA limit rate to once every 1800 seconds 2-2 Rate Limit generation 20001 20057 NA 900 NA limit rate to once every 900 seconds 3-1 Custom Suppress CDR 50002 60023 5 NA On location change: generation for destination = ‘Atlanta’ usages <5 when device moves to Roaming (‘Atlanta’) 3-2 Custom Limit generation 60023 70023 NA 900 On location change: rate to once every destination = ‘Atlanta’ 900 seconds when device moves to Roaming(‘Atlanta’)

In one example, rules engine 240 may filter out a charging volume based on the usage threshold rules illustrated in Table 1. Consider a UE with a SUPI of 10002 that generates a charge record of usage two bytes. Based on the SUPI, rules engine 240 may identify the applicable rule as Rule 1-1. Example pseudocode for executing Rule 1-1 is provided as follows.

Usage Rule-x -> { IF ( (SUPI.usage <= x.threshold)) then return SKIP_CDR_GENERATION; ELSE Break; }

In another example, rules engine 240 may rate-limit CDR generation based on the rate-limit filtering rules illustrated in Table 1. Consider a UE with a SUPI of 30002 that generates a charge record of usage ten bytes. Based on the SUPI, rules engine 240 may identify the applicable rule as Rule 2-1. Example pseudocode for executing Rule 2-1 is provided as follows.

Ratelimit Rule-x -> { IF ( SUPI is in range (Min(SUPI), Max(SUPI)) then prepare ‘Response Triggers’ for CHF 140 to limit generation rate to once per 1800 seconds ELSE Break; }

In another example, rules engine 240 may alter CDR generation behavior based on a location change event, as indicated by third-party services 220, based on the custom rules illustrated in Table 1. Consider a UE with a SUPI of 60024 that moves from a home location (e.g., San Jose) to a remote network location (e.g., Atlanta). In this roaming scenario, the entity associated with billing system intends for CDRs to be generated once every fifteen minutes. Based on the SUPI, rules engine 240 may identify the applicable rule as Rule 3-2. Example pseudocode for executing Rule 3-2 is provided as follows.

Location Rule-x -> { IF ( inRoaming(SUPI) && SUPI.location= x.Location ) then prepare ‘Response Triggers’ for CHF 140 to limit generation rate to once per 900 seconds ELSE ( E1.Dx.Loc= Loc2 ) then s-NSSAI=s-NSSAI-1-2 }

With continued reference to FIG. 1, FIG. 3 illustrates a sequence flow diagram of an example method 300 for managing one or more rules that control whether or when one or more CDRs are to be provided to billing system 130. Method 300 demonstrates interactions between CFF 180 and other 5G components for an example charging record event in order to filter 5G traffic. Method 300 may involve operations performed by various actors, including UE 305, Access and Mobility Management Function (AMF) 310, SMF 315, CHF 140, CFF 180, CGF 160, Billing System 130, and entity 320. UE 305 may be a UE for which charging data is being reported. AMF 310 may be configured to manage connection and mobility tasks on behalf of UE 305. SMF 315 may be network function 110. Entity 320 may be an entity associated with billing system 130.

At operation 325, CFF 180 obtains one or more rules from entity 320 (e.g., via Control Center 210). The one or more rules may be generated by entity 320. This may allow entity 320 to configure filtering rules on CFF 180 for one or more devices, such as UE 305. At operation 330, AMF 310 obtains a session establishment request from UE 305. At operation 335, SMF 315 obtains a Session Management (SM) create context request (e.g., an Nsmf_PDUSession_CreateSMContext Request) from AMF 310. At operation 340, SMF 315 may make other calls to actors such as Unified Data Management (UDM), Policy Control Function (PCF), etc. At operation 345, CHF 140 obtains a create converged charging request from SMF 315. The create converged charging request may be a Nchf_ConvergedCharging service sent to CHF 140 to create, update, or release the charging resource.

At operation 350, CFF 180 obtains a charging filter request from CHF 140. This may help CHF 140 to enforce one or more rules that control whether or when one or more CDRs associated with UE 305 are provided to billing system 130. For instance, the charging filter request may prompt CFF 180 to check for one or more filtering rules associated with UE 305 (e.g., the rules obtained by CFF 180 during operation 325). The filtering rules may be volume-based or rate-limit-based.

At operation 355, CFF 180 identifies parameters for triggers to be set for UE 305 based on the one or more rules. At operation 360, CFF 180 obtains the filtering policy/rule(s) to be applied for UE 305. At operation 365, CFF 180 provides a charging filtering response to CHF 140. The charging filtering response may indicate whether a CDR update should occur (e.g., whether the incoming charging data should be discarded) based on the one or more filtering rules, and may further include any triggers to be set by SMF 315. For example, if the relevant rule(s) is/are volume-based, the charging filtering response may indicate whether to discard the CDR depending on whether the amount of bytes in the CDR is below a minimum threshold. If the relevant rule(s) is/are rate-limit-based, the charging filter response may indicate how often CDRs associated with UE 305 should be sent to billing system 130.

At operation 370, if CFF 180 indicates that the CDR update should occur (e.g., the charging data should not be discarded), CHF 140 forwards the CDR request to CGF 160 over the Ga interface. At operation 375, CGF 160 generates the CDR files and forwards the CDR files to billing system 130 over the Bd interface. At operation 380, CHF 140 provides, to SMF 315, a create converged charging response (e.g., a Hypertext Transfer Protocol (HTTP) 2xx response indicating successful processing of the request). For example, if the rule(s) is/are rate-limit-based, the create converged charging response may indicate how often SMF 315 should send charging data to CHF 140. SMF 315 may determine when to send charging volumes to CHF 140 based on the create converged charging response. Once session establishment is accepted, AMF 310 may make calls that request the Protocol Data Unit (PDU) session, to the cellular access point (e.g., gNodeB) to which UE 305 is attached. The gNodeB may send a configuration message to UE 305.

Thus, as demonstrated by method 300, CFF 180 may interact with CHF 140 to filter traffic between CHF 140 and billing system 130. In one example, CFF 180 interacts with CHF 140 to identify benign transactions/usage sessions based on filtering rules defined by entity 320 and skip/avoid sending corresponding CDRs to billing system 130. In another example, CFF 180 interacts with CHF 140 to limit record generation rate/frequency based on rate-limit rules defined by entity 320 using the interface between CHF 140 and SMF 315. In still another example, CFF 180 interacts with third-party services 220 to allow custom-defined filtering behavior for given events.

With continued reference to FIGS. 1 and 2, FIG. 4 illustrates a block diagram of an example system 400. System 400 includes network function 110, converged charging system 120 (including CHF 140, CGF 160, and CFF 180), Control Center 210, third-party services 220, operator billing system 410(1), and enterprise billing system 410(2). In this example, CGF 160 includes CDR aggregator 420 and CDR splitter 430, and CFF 180 includes rules engine 240, notification service 250, rules repository 260, and converged charging rate resolver 440.

Unlike system 200, system 400 includes multiple billing systems, namely operator billing system 410(1) and enterprise billing system 410(2). Operator billing system 410(1) may have a network operator associated therewith, and enterprise billing system 410(2) may have an enterprise associated therewith. Operator requirements regarding whether or when CDRs should be provided to operator billing system 410(1) may differ from enterprise requirements regarding whether or when CDRs should be provided to enterprise billing system 410(2).

In one example, it may be desirable to provide operator billing system 410(1) with CDRs that carry an amount of information above a minimum threshold, and provide enterprise billing system 410(2) with CDRs that carry any amount of information. For instance, the enterprise may be interested in zero-byte CDRs to track UE keep-alive messages even when the UE is not in use, whereas the operator may not be interested in keep-alive zero-byte CDRs. In another example, it may be desirable to provide operator billing system 410(1) with CDRs at a finer granularity to meet network operation management needs (e.g., once every second), and provide enterprise billing system 410(2) with CDRs at a lower granularity (e.g., once every fifteen minutes).

Accordingly, CFF 180 may support filtering behaviors for different rules defined by different enterprise and operator entities to enable suppressing certain CDRs based on entity intent. The CDRs may be associated with the same UE but may be provided to operator billing system 410(1) and enterprise billing system 410(2) according to different usage thresholds or at different rates. Thus, CFF 180 may provide the ability for different CDR generation frequencies, or generation of different sets of CDRs, based on different classes of entities or different entity policies. In one example, CFF 180 may support divergent filtering behaviors for different network entities (e.g., enterprises, operators, etc.) for a single charging event in order to allow entity intent-based filtering behavior by allowing entities to define separate policy rules for a single charging event. This may enable suppressing CDR generation based on usage volume threshold policies, and/or rate-limiting CDR generation whereby CDRs are generated at different rates, for the same UE but for different entities.

While system 100 illustrates operator billing system 410(1) and enterprise billing system 410(2), it will be appreciated that techniques described herein may be applied to any suitable number of billing systems associated with any suitable entities. For instance, there may be multiple enterprise billing systems associated with respective enterprises that have different requirements from each other. In an example involving multiple enterprise billing systems, one enterprise may require CDRs every fifteen minutes, whereas another enterprise may require CDRs every thirty minutes. Enterprise requirements may also vary based on a number of UEs are associated with, or expected to be associated with, the relevant billing system. Multiple operator billing systems associated with respective operators may also have different requirements from each other.

CGF 160 may communicate with CFF 180 to gain context for different generation rates for different entities (e.g., operator billing system 410(1) and enterprise billing system 410(2)). CGF 160 may use any context received from CFF 180 to implement CDR aggregator 420 and CDR splitter 430. Briefly, CDR aggregator 420 may handle CDR aggregation to support different rates of generation for a given UE according to one or more defined filtering rules, and CDR splitter 430 may provide, to different entities (e.g., both operator billing system 410(1) and enterprise billing system 410(2)), multiple CDR output streams associated with a given UE for a charging record.

CFF 180 may provide one or more rules to control whether or when the one or more CDRs associated with a UE are to be aggregated before being provided to operator billing system 410(1) and/or enterprise billing system 410(2). In one example, CGF 160 may obtain one or more usage records, consult with CFF 180 for any applicable rate-limit filtering policies/rules, and aggregate the usage records according to the defined rules. Consider an scenario in which the operator defines a rule for operator billing system 410(1) to receive a CDR for the UE once every fifteen minutes, and the enterprise defines a rule for enterprise billing system 410(2) to receive a CDR for the UE once every thirty minutes.

Here, CDR aggregator 420 may obtain a CDR to be provided to enterprise billing system 410(2) every fifteen minutes. However, because enterprise billing system 410(2) is to obtain a CDR every thirty minutes, CDR aggregator 420 may wait an additional fifteen minutes for an additional CDR to be provided to enterprise billing system 410(2) and aggregate the CDR and the additional CDR into one aggregated CDR which is provided to enterprise billing system 410(2). Enterprise billing system 410(2) may thus obtain an aggregated CDR every thirty minutes in this manner. It will be appreciated that CDR aggregator 420 may also/alternatively determine whether to generate CDRs for a usage record according to usage filtering rules defined in CFF 180.

CFF 180 may also/alternatively provide one or more rules to control whether or when one or more CDRs associated with a UE are to be split before being provided to operator billing system 410(1) and enterprise billing system 410(2). CDR splitter 430 may interact with operator billing system 410(1) and enterprise billing system 410(2) to provide any desired CDR streams for north-bound processing. Consider the aforementioned scenario in which the operator defines a rule for operator billing system 410(1) to receive a CDR for the UE once every fifteen minutes, and the enterprise defines a rule for enterprise billing system 410(2) to receive a CDR for the UE once every thirty minutes. Here, CDR splitter 430 may split an aggregated CDR once every thirty minutes to generate a first CDR for operator billing system 410(1) and a second CDR for enterprise billing system 410(2).

Thus, in one specific example, at a first point in time CDR splitter 430 splits the CDR and sends the split CDRs to operator billing system 410(1) and enterprise billing system 410(2). Fifteen minutes later, CDR splitter 430 refrains from the splitting the CDR and the CDR is sent to operator billing system 410(1) but not to enterprise billing system 410(2). Fifteen minutes later, the cycle begins repeats, with CDR splitter 430 splitting the CDR and sending the split CDRs to operator billing system 410(1) and enterprise billing system 410(2). Thus, operator billing system 410(1) obtains a CDR once every fifteen minutes, and enterprise billing system 410(1) obtains a CDR once every thirty minutes. It will be appreciated that CDR splitter 430 may also/alternatively determine whether to generate CDRs for a usage record according to usage filtering rules defined in CFF 180.

Converged charging rate resolver 440 may be responsible for resolving trigger condition conflicts for a given UE amongst multiple rate-limit filtering rules (e.g., conflicting filtering policies) on behalf of network function 110 and support desired CDR rate trigger generation for the operator and the enterprise. In one example, converged charging rate resolver 440 determines that a rule controls whether or when the one or more CDRs associated with a UE are to be provided to operator billing system 410(1) based on a first frequency at which the one or more CDRs are to be provided to operator billing system 410(1). Converged charging rate resolver 440 further determines that a second rule controls whether or when the one or more CDRs associated with the UE are to be provided to enterprise billing system 410(2) based on a second frequency at which the one or more CDRs are to be provided to enterprise billing system 410(2). In one example, converged charging rate resolver 440 may fetch all applicable rate-limit policies for the UE and the given charging record.

In this example, the second frequency is a multiple of the first frequency. For instance, the first frequency may be once every fifteen minutes, and the second frequency may be once every thirty minutes. In other words, the operator may define a rule for operator billing system 410(1) to receive a CDR for the UE once every fifteen minutes, and the enterprise may define a rule for enterprise billing system 410(2) to receive a CDR for the UE once every thirty minutes.

Converged charging rate resolver 440 may provide one or more rules that control whether or when the one or more CDRs associated with the UE are to be provided to operator billing system 410(1) and enterprise billing system 410(2) based on the first frequency (e.g., once every fifteen minutes). In one example, converged charging rate resolver 440 may compute the minimum trigger duration (e.g., the minimum time rate-limit frequency, which is fifteen minutes in this example) and send an indication of the trigger duration (e.g., fifteen minutes) to CHF 140. This may prompt CHF 140 to instruct network function 110 to restrict the rate limit for future usage records.

Table 2 below illustrates example rules that may be stored by rules repository 260 defined by the operator for operator billing system 410(1) and by the enterprise for enterprise billing system 410(2) for various UEs. The “Defined by Role” column designates the rule as belonging to the enterprise or the operator, and CFF 180 may support desired behavior for both entities accordingly. The numbers in the “Threshold” column may be measured in bytes, and the numbers in the “Rate Limit” column may be measured in seconds.

TABLE 2 Rule Rule Defined Min Max Rate ID Type Description By Role SUPI SUPI Threshold Limit Custom Trigger 1-1 Usage Suppress CDR Enterprise 10001 10010 5 NA NA generation for usages <5 1-2 Usage Suppress CDR Operator 10001 10010 15  NA NA generation for usages <15 2-1 Rate Limit the Enterprise 30001 30010 NA 1800  NA limit generation rate to per 1800 seconds frequency 2-2 Rate Limit the Operator 30001 30010 NA 900 NA limit generation rate to per 900 seconds frequency 3-1 Custom Suppress CDR Enterprise 50002 60023 5 NA On location change: generation for destination = ‘Atlanta’ usages <5 when device moves to Roaming (‘Atlanta’) 3-2 Custom Suppress CDR Operator 50002 60023 5 NA On location change: generation for destination = ‘Atlanta’ usages < 5 when device moves to Roaming (‘Atlanta’)

In one example, rules engine 240 may filter out a charging volume based on the usage threshold rules illustrated in Table 2. Consider a UE with a SUPI of 10002 that generates a charge record of usage two bytes. Based on the SUPI, rules engine 240 may identify the applicable rule as Rules 1-1 and 1-2. Example pseudocode for executing Rules 1-1 and 1-2 is provided as follows.

Usage Rule-x, Usage Rule-y -> { minThresholdUsage = findMin(x.threshold , y.threshold) IF ( (SUPI.usage <= minThresholdUsage)) then return SKIP_CDR_GENERATION; ELSE Break; }

Once the CDRs are generated, different streams may be generated for operator billing system 410(1) and enterprise billing system 410(2) (e.g., by CDR splitter 430) according to the following example pseudocode.

Enterprise Usage Rule-x -> { IF ( (SUPI.usage <= x.threshold)) then return SKIP_CDR_GENERATION; ELSE Append the CDR to enterprise data stream; } Operator Usage Rule-y -> { IF ( (SUPI.usage <= y.threshold)) then return SKIP_CDR_GENERATION; ELSE Append the CDR to Operator data stream; }

In another example, rules engine 240 may rate-limit CDR generation based on the rate-limit filtering rules illustrated in Table 2. Consider a UE with a SUPI of 30002 that generates a charge record of usage ten bytes. Based on the SUPI, rules engine 240 may identify the applicable rule as Rule 2-1 and 2-2. CDRs may be generated and aggregated for operator billing system 410(1) and enterprise billing system 410(2) (e.g., by CDR aggregator 420) according to the following example pseudocode.

RateLimit Rule-x , RateLimit Rule-y -> { minRatelimit = findMin(x.ratelimit , y.ratelimit) Prepare CHF 140 response triggers for records generation at minRatelimit frequency. }

With continuing reference to FIGS. 1-3, FIG. 5 illustrates an example sequence flow diagram of method 500 for managing one or more rules that control whether or when one or more CDRs are to be provided to operator billing system 410(1) and enterprise billing system 410(2) based on one or more frequencies at which the one or more CDRs are to be provided to operator billing system 410(1) and enterprise billing system 410(2). Method 500 relates to multiple rate limit filtering rules for various entities that may be supported for a single UE (e.g., UE 305), to enable rate-limiting policies based CDR generation. Method 500 may involve operations performed by various actors, including Control Center 210, CFF 180, CHF 140, SMF 315, CGF 160, and enterprise billing system 410(2).

At operation 505, CFF 180 (e.g., rules engine 240) obtains, from Control Center 210, respective policy setup instructions (e.g., filtering rules) for the operator and the enterprise. This may allow entities to configure policies on CFF 180 (e.g., via Control Center 210). At operation 510, CHF 140 obtains a converged charging request from SMF 315. The converged charging request may be a request for a CDR trigger. At operation 515, CFF 180 obtains a request for a charging time trigger from CHF 140. The request may permit CHF 140 to consult with CFF 180 to determine the trigger.

At operation 520, CFF 180 (e.g., rules engine 240) identifies the relevant policies for UE 305. At operation 525, CFF 180 (e.g., converged charging rate resolver 440) computes a minimum time granularity trigger. By way of example, different entities may request different CDR rates, and converged charging rate resolver 440 may identify the minimum CDR rate. For instance, if the operator requests one or more CDRs once every fifteen minutes, and the enterprise requests one or more CDRs once every thirty minutes, converged charging rate resolver 440 may identify the minimum granularity as fifteen minutes.

At operation 530, CFF 180 provides the time trigger (e.g., fifteen minutes) to CHF 140. At operation 535, CHF 140 provides the time trigger to SMF 315. At operation 540, CHF 140 obtains usage data (e.g., a CDR) from SMF 315 after the trigger duration (e.g., fifteen minutes). At operation 545, CHF 140 automatically forwards the usage data to CGF 160 in response to obtaining the usage data from SMF 315.

At operation 550, CGF 160 (e.g., CDR aggregator 420 and/or CDR splitter 430) consults with CFF 180 to determine whether aggregation/splitting is needed (e.g., which of operator billing system 410(1) and enterprise billing system 410(2) should receive data, and when). For example, CGF 160 may provide a policy details fetch request to CFF 180, and CFF 180 may respond with the appropriate rules. At operation 555, CGF 160 (e.g., CDR aggregator 420) performs CDR aggregation on a per-policy basis. At operations 560 and 565, CGF 160 (e.g., CDR splitter 430) provides, to operator billing system 410(1) and enterprise billing system 410(2), multiple output CDR streams per policy.

With continuing reference to FIGS. 1-3, FIG. 6 illustrates an example sequence flow diagram of a method 600 for managing one or more rules that control whether or when one or more CDRs are to be provided to operator billing system 410(1) and enterprise billing system 410(2) based on one or more amounts of information to be carried in the one or more CDRs. Method 600 relates to multiple rate limit filtering rules for various entities may be supported for a single UE (e.g., UE 305), to enable rate-limiting policy based CDR generation. Method 600 may involve operations performed by various actors, including Control Center 210, CFF 180, CHF 140, SMF 315, CGF 160, operator billing system 410(1), and enterprise billing system 410(2).

At operation 605, CFF 180 (e.g., rules engine 240) obtains, from Control Center 210, respective policy setup instructions (e.g., filtering rules) for the operator and the enterprise. This may allow entities to configure policies on CFF 180 (e.g., via Control Center 210). At operation 610, CHF 140 obtains a converged charging request from SMF 315. The converged charging request may be a request for a CDR trigger. At operation 615, CFF 180 obtains a request for a charging trigger from CHF 140. The request may permit CHF 140 to consult with CFF 180 to determine the trigger. At operation 620, CFF 180 provides the charging trigger (e.g., a minimum threshold such as 1 MB) to CHF 140. At operation 625, CHF 140 provides a converged charging response to SMF 315. At operation 630, CHF 140 obtains CDR data from SMF 315. At operation 635, CHF 140 sends the CDR data to CGF 160 if the CDR data carries more information than the minimum threshold.

At operation 640, in response to obtaining the CDR data from CHF 140, CGF 160 (e.g., CDR splitter 430) consults with CFF 180 to determine whether splitting is needed (e.g., which of operator billing system 410(1) and enterprise billing system 410(2) should receive data, and when). For example, CGF 160 may provide a policy details fetch request for UE 305 to CFF 180, and CFF 180 may respond with the appropriate rules. At operation 645, CGF 160 (e.g., CDR splitter 430) performs CDR splitting on a per-policy basis. At operation 650, CGF 160 (e.g., CDR splitter 430) consults with CFF 180 to determine the threshold limit for the relevant policy. At operations 655 and 660, CGF 160 (e.g., CDR splitter 430) provides, to operator billing system 410(1) and enterprise billing system 410(2), multiple CDR output streams per policy. Thus, CDRs may be generated based on usage volume threshold policy, and multiple usage-based filtering rules (e.g., for enterprises/operators) may be supported for a single device (e.g., UE 305).
